The fermentation and granulation processes of the sheep manure organic fertilizer production line are key steps in producing high-quality organic fertilizers, ensuring the nutrient content, biological activity, and physical properties of the organic fertilizer. The following is a detailed description of the fermentation and granulation processes in the sheep manure organic fertilizer production line:
1. Fermentation process
1.1 Raw material pretreatment
Raw material collection: Collect fresh or dried sheep manure to ensure that the raw materials are free of impurities.
Crushing and mixing: Crush sheep manure and mix it with appropriate amounts of organic matter such as straw and sawdust, as well as microbial agents, to improve fermentation efficiency and fertilizer structure.
1.2 Composting fermentation
Stacking: Stacking the mixed raw materials into strips or placing them in a fermentation chamber, with the height and width of the pile determined by the fermentation equipment and site conditions.
Fermentation initiation: The fermentation process is initiated by adding microbial agents, and the temperature naturally increases during the fermentation process, reaching 60-70 ℃, which helps to kill pathogens and weed seeds.
Pile flipping: Regularly flip the pile to provide oxygen, promote aerobic microbial activity, and ensure uniform fermentation. The flipping frequency depends on the fermentation temperature and the state of the raw materials.

1.3 Post fermentation treatment
Cooling: After fermentation is complete, the material needs to be cooled to room temperature to avoid the influence of high temperature on the subsequent granulation process.
Crushing: Grind the cooled material again to ensure that the particle size is suitable for granulation.
2. Granulation process
2.1 Particle Forming
Raw material pre wetting: The moisture content of the raw material can be appropriately increased as needed to improve granulation efficiency and particle strength.
Granulation: Use organic fertilizer granulators (such as disc granulators, roller extrusion granulators, etc.) to process raw materials into granules. The type and parameters of the granulator need to be selected based on the characteristics of the raw materials and the target particle size.
2.2 Particle screening and processing
Screening: Use vibrating screens and other equipment to screen the pelletized material, removing particles that are too large or too small.
Crushing and re granulation: Crushing and re granulation the selected unqualified particles until they meet the requirements.
Drying and Cooling: Dry the granulated particles to remove excess moisture, and then cool them to a suitable temperature to ensure their stability.
2.3 Packaging and Storage
Quantitative packaging: Use a packaging machine to quantitatively package the processed granular fertilizers.
Storage: Store packaged fertilizers in a dry and ventilated environment to avoid moisture and contamination.
The fermentation and granulation processes of the sheep manure organic fertilizer production line need to be adjusted according to the characteristics of the raw materials, equipment conditions, and market requirements to ensure the quality and market competitiveness of the final product.
